The centrifuge tube automatic capping machine is a highly efficient automated equipment designed for the assembly of plastic centrifuge tube caps. Its main function is to automatically complete a series of operations such as capping, tightening, and testing of the filled centrifuge tube to ensure that the tube is tightly sealed, the cap is in place, there is no leakage, and there is no damage. The equipment can be operated independently or integrated into the centrifuge tube automatic production line, and form a complete intelligent manufacturing system with the tube cutting machine, filling machine, core plugging machine, screen printing machine, etc.

　　1. Core structure and workflow

　　The centrifuge tube automatic capping machine is usually composed of the following main parts:

　　Capping feeding system: The vibrating plate or lifting machine is used to automatically straighten and transport the threaded cap to the capping station to avoid manual intervention.

　　Automatic clamping and positioning device: The mechanical clamp or servo drive structure accurately positions the tube body to ensure that the tube body is stable and does not deviate when the cap is screwed.

　　Capping execution system: The high-precision electric capping head controls the rotation speed and torque to ensure that each centrifuge tube is tightened without slipping or bursting.

　　Detection and rejection system: Automatically detect whether the capping is in place through sensors or visual systems, and automatically reject products that fail to cap, ensuring consistent product quality.

　　Conveying and online module: It can be connected to the automated assembly line to achieve seamless connection with the previous and next processes.

　　2. Technical advantages of centrifuge tube automatic capping machine

　　High-efficiency production: 40 to 100 centrifuge tube capping operations can be completed per minute, far exceeding the efficiency of manual operation, and adapting to the delivery needs of large-volume orders.

　　High-precision torque control: The capping head has a built-in torque adjustment module to ensure that the screwing force of each cap is consistent, improve the sealing effect, and avoid sample leakage.

　　Compatible with multiple specifications: Suitable for centrifuge tubes of various specifications (such as 1.5ml, 5ml, 15ml, 50ml, etc.) and different types of caps (with sealing rings, explosion-proof caps, etc.), changing specifications is quick and convenient.

　　Stable operation, intelligent alarm: The whole machine adopts PLC+touch screen control system, which is intuitive to operate and sensitive to response. Abnormal conditions will be alarmed and stopped in real time to ensure safe and stable production.

　　Clean and corrosion-resistant design: The main body of the equipment is made of 304 stainless steel and anodized aluminum, which meets the GMP clean production standards and is suitable for clean workshops and laboratory consumables factories.

　　The automatic capping machine for centrifuge tubes not only improves the production efficiency and product quality of centrifuge tubes, but also marks an important step towards intelligent and standardized manufacturing of experimental consumables. For companies committed to increasing production capacity, reducing costs and ensuring quality, the introduction of such automated equipment is undoubtedly a high-return strategic investment. In the wave of sustainable development of biotechnology and medical health, it will play an increasingly critical role.
